MACHINE FOR PRESSING- SEAMS.

Specification of Letters Patent.

Patented Apr. 20, 1920.

Application filed June 23, 1919. Serial No. 306,087.

To all whom it may concern:

Be it known that I, JAooB DENEMARK, a

citizen of Russia, residing at Trenton,

Mercer county, State of New Jersey, have invented certain new and useful Improvements in Machines for Pressing Seams, of which the following is a full, clear, and exact description.

This invention relates to improvements in pressing or ironing devices, and has for one of its objects to provide a device of this nature which is articularly arranged or adapted for pressing seams. To carry out my invention, I provide a continuously rotatable pressing or ironing element, that is to say, continuously rotatable while pressing or ironing seams, and special means to heat same,- preferably by electricity. Other features of improvement will hereinafter apear. p I will now in detail describe the embodiment of my invention which is illustrated in the accompanying drawings, wherein .Fi ure 1 is a side elevation, the presser foot eing removed;

Fig. 2 is an enlarged sectional view ofthe lower or under pressing element;

Fig. 3 is a longitudinal sectional view thereof, the take-up spring being omitted;

Fig. 4 is an end view looking from the left in Fig. 1;

Fig. 5 is a plan view, the operating gears being omitted; and

Fig. 6 is a fragmentary perspective view of the presser-foot.

As herein arranged, my improved pressing device consists of a standard 7 having pivotally connected thereto at 8 an arm 9 which in turn has secured thereto, by bolts 10, a bracket 11, which in combination with the standard and arm 9 rotatably supports a shaft 12, which carries one of the pressing elements 13, the cooperating pressing element 14 being carried by a shaft 15 supported by the standard 7 adjacent the lower end. thereof. The shaft 12 has connected thereto, by means of universal joint members 16 and 17, a stub-shaft 18, to the outer end of which is secured a gear 19 meshing with a similar gear 20 on the shaft 15. The shaft 15 also carries a belt-pulley 21 and hand-wheel 22. To heat the upper pressing element or drum 13, which is hollow or cupshaped, I employ a drum 23 provided interiorly thereof with a resistance coil 24 suitably connected by leads 25 and 26 to an electrical circuit. The leads 25 and 26 connect the coil 24 to a socket 27 carried by a supplemental bracket 28, said socket being arranged to receive a plug 29 which is connected to the main circuit wires within the cable 30. The supplemental bracket 28 also supports a socket 31 to receive a lamp 32, connected by leads 33 and 34 to the terminal within socket 27 to which the leads 25 and 26 are connected. The lamp "32 acts as a telltale to notify the operator whether the current is on or off hence injury by burning Wlll be less liable, as the operator can tell whether the iron is heated or not, or whether the circuit is complete or not. The heaterdrum 23 is stationary and projects into the pressing drum 13, said heater-drum being secured to bracket 11 by a nut 35 which engages a threaded stud 36 carried by the heater-drum 23. The lower pressing element or drum 14 carries a friction band 37 to facilitate the feeding of the goods to be pressed. Said friction-band is engaged by a feed belt 38. which also passes over an idler 39 carried by a plate 40, extending from the standard 7. The idler 39 is located a sufiicient distance from the lower drum 14 to provide a straight run 41 which passes over a portion of the top surface of the plate 40. To maintain the friction-band 37 taut I employ a take-up device or spring 42 carrying rings 43 and 44 to engage hooks carried by the band 37 at its ends. The ends of the band 37 pass through a slot or opening 14 in the wall of the. lower drum 14, which is hollow or cup-shaped, the walls of said opening being rounded as at 44. The tension of the spring will maintain the band taut, thereby preventing wrinkles or kinks which might be caused by a slack band. The spring 42 is passed around a cylindrical support 45 having an annular groove 46 to maintain the spring in position. The support 45 is preferably loosely mounted upon the shaft 12 in order that it can be slipped off the shaft should it be necessary to remove the take-up spring. T0 force the pressing devices together, I provide springs 47 which encircle posts 48. The posts 48 at their lower ends are secured to brackets 49 which project from the standard 7 The posts at the upper ends, pass through openings 50 in a bracket 51 projecting from the hubportion of the arm 9. The springs act to force bracket 51 upwardly, thereby forcing the upper pressing drum 13 downwardly the goods, I provide a lever 52 pivoted at 53 to the standard 7 (see Fig. 4). The lever 52 is connected by a link 54 to an auxiliary lever 55 pivoted at 56 to an extension or bracket 57 projecting from the standard 7.-

The auxiliary lever 55 is connected by a link x 58 to the bracket 51 which extends from the hub portion of the arm 9. WVhen lever 52 is depressed, arm 9 will be raised at its outer end, thereby raising the upper pressing drum away from the goods. To main- -tain the drum 13 in raised position, I provide a stop 59 pivotally connected to lever 52. To maintain lever 52 depressed stop 59 will be moved to a position under bracket 49, after which the springs will be held in contracted condition and the drum 13 raised.

To cooperate with the pressing drums, I provide a presser-foot 60, to which a post 61 is pivotally connected, at 62, to ears 63 on said presser-foot. The post 61 consists of a rod 64 and block 65, which is secured to a knee 66 which in turn is pivotally connected to the ears 63. The upper end of rod 64 passes loosely through a supportin -member 66 carried by bracket 11, said bracket carrying a guide 67 having a slot 68 to slidably receive a tongue 69 carried by a block 70 secured to rod 64 at its upper end. To force the presser-foot downwardly, I employ a spring 71. The hub of the support 66 limits the downward movement of the resser-foot when the drum 13 is in raised position. \Vhen the drum is lowered, the presser-foot will yield, placing spring 71 under increased tension; hence said presser-foot will be firmly forced against the goods to be pressed. The resser-foot 60 carries a fin 73 which acts as a sight or guide for the operator while pressing the goods to keep the seam centered relative to the drum, thus facilitating the proper positioning of the seams while the goods are being pressed. The seam to be pressed is placed upon the feedbelt 38 between it and drum 13, after which the said drum is lowered to rest upon the seam. After drum 13 has become sufficiently heated, either before the goods are positioned or after, the belt-wheel 21 will be rotated by a belt (not shown), either manually or by power. The rotation of the beltpulley will rotate drums 13 and 14, thereby causing belt 38 to travel, as per arrow Fig. 4, carrying the goods in said direction. As the seams pass between the drums or between drum 13 and belt 38, they will become pressed or ironed, due to the heated drum and pressure exerted thereupon. The drum 13 will be heated by the heat emanating or radiating from drum 23, as said pressing-drum 13 and heating drum 23 are separated by a slight air gap 74. But it will be understood that other heating means may be employed, and also that various details of construction may be modified with out departing from the scope of my inven tion.

Having described my invention, what I claim is 1. In a pressing device, a standard, a stub-shaft carried thereby, an arm pivotally connected to said standard, a shaft carried by said arm, a pressing-drum carried by the shaft supported by said arm, a universal joint connecting said shafts, means to support the goods to be pressed, and means to actuate the arm to force the pressing-roll carried thereby against the goods to be pressed.
